GT RootZone – 250mL

Based on nature. Rooted in science – GT RootZone is here.

GT RootZone is an organic-based biostimulant designed to put root health first. It supports a bigger, stronger, healthier root zone at every stage of the plant lifecycle, helping plants recover from stress, resist root rot, and thrive from the roots up .

Perfect for:

  • Plants grown in pots, containers, hydroponics, semi-hydro, and soil-based mixes.
  • Houseplants, orchids, aroids, foliage plants, ferns, edibles, and succulents where root health is critical.
  • Cuttings and seedlings needing a strong start for faster, more reliable propagation.
  • Plants recovering from root rot, transplant stress, overwatering, or root damage.
  • Slow-growing plants in tired or compacted mixes where nutrient uptake is compromised.

Why GT RootZone stands out:

  • Organic-based biostimulant developed around nature’s rule: the stronger the roots, the stronger the plant.
  • Rich in natural growth hormones from marine extract to drive vigorous new root and shoot growth.
  • Supports nutrient uptake, reducing nutrient lockout and fertiliser salt build-up and burn.
  • Helps protect against common stresses, including root rot, transplant shock, and fertiliser stress.
  • Gentle yet super-concentrated – a little goes a long way and is ideal for regular use with your usual fertiliser.

How to Use:

  • Use throughout the plant’s lifecycle, best applied every time you water.
  • Cuttings and seedlings: use at 0.5 mL per 1 L of water.
  • Juvenile to mature plants: use at 1 mL per 1 L of water.
  • Use alongside your usual fertiliser – add RootZone to the same water as GT CCS (for cuttings/seedlings) or GT Focus fertilisers (for established plants).

Ingredients (w/v):

  • Marine extract (Ascophyllum nodosum) – natural source of cytokinins, gibberellins and auxins.
  • Fulvic acids – enhance nutrient uptake and support root and shoot growth.
  • Amino acids – support chlorophyll production, photosynthesis, and stronger, denser growth.
  • Thiamine (Vitamin B1) – supports the plant’s natural defence system and reduces transplant stress.
  • Potassium – supports overall plant health and balanced growth.

Safety Note:
Gentle but concentrated. Use as directed. Avoid contact with eyes and do not ingest. Store upright in a cool, dark place and keep out of reach of children and pets. RootZone concentrate has a natural earthy, vitamin-like smell which largely disappears once diluted.
